Parameters

Description

Only some of the window attributes or the access speed field may
be modified by this request. The csx_MapMemPage(9F) function is also used to set the
offset into PC Card memory to be mapped into system memory for paged
windows. The csx_RequestWindow(9F) and csx_ReleaseWindow(9F) functions must be used to change the window base
or size.

Window points to Common Memory area. Set this to map the window to Common Memory.

WIN_MEMORY_TYPE_AM

Window points to Attribute Memory area. Set this to map the window to Attribute Memory.

WIN_ENABLE

Enable Window. The client must set this to enable the window.

WIN_ACCESS_SPEED_VALID

AccessSpeed valid. The client must set this when the AccessSpeed field has a value that the client wants set for the window.

AccessSpeed

The bit definitions for this field use the format of the extended speed byte of the Device ID tuple. If the mantissa is 0 (noted as reserved in the PC Card 95 Standard), the lower bits are a binary code representing a speed from the list below. Numbers in the first column are codes; items in the second column are speeds.

0

250 nsec

2

200 nsec

3

It is recommended that clients use the csx_ConvertSpeed(9F) function to generate the appropriate AccessSpeed values rather than manually perturbing the AccessSpeed field.
